Fig. 3 is an elevationof a portion of the rake at an enlarged scale, prior to bending one of the flanges of the tooth-supporting bar down upon the plates on which the teeth are formed;

Fig. 4 is a sectional view at an enlarged scale on line 41 of Fig. 2; and

Fig. 5 is an elevation of two of the tooth plates illustrating the manner of dieing them out of a strip of steel. 7

Referring to the drawings, and to the em bodiment of the invention which is illustrated therein, there is shown a rake comprise ing a handle 10, herein a cylindrical bar of wood, to which there is secured, as by a rivet 11, a transverse bar 12, the latter in the present example presenting a channel 13 (see Fig. 1) between two flanges 14 and 15. As herein shown, the bar is curved rearwardly thereb to cause a divergence of the teeth now to be escribed.

One convenient way of making the teeth is to pass a continuous strip of flexible steel between a pair of cutting and punching dies, which, by one stroke of the punch press cuts ofi apiece of appropriate length, andpunches it to form two plates 16 and 17, one having a pair of spaced teeth 18, having rounded ends 19, and the other having a single tooth 20, having a rounded end 21. At the same time, two holes 22 are punched in the plate 16, and two holes are punched in the plate 17. Thus the two plates are formed without waste of metal, except for that which is punched lar to each other (see Fig. 3) T from its point of attachment to the handle,

out in forming the holes 22 and-23.1: It is desirable that'the two teeth 18 divergev'slightly toward their-free ends. "This is conveniently "accomplished in the present case by a die which spreads themapart slightly, im-

mediately following the cutting operation. 1

The bar 12 is'at first an' angle-bar,,that isto say, itsflangesl and Mareplerpendicue plates16 and 17 are placed in an alternating series 00 upon the flange 15, andthey' are conveniently secured to'thelatter by extruding the flange to present eyelets24: integral therewith and pushed through the perforations '(see Fig. 4), and headed. over as at 25 after the fashion. of 05 tubular rivets upon; thefront faces. OfrthB plates 16. and 17 Thea-rrangement of these fastening elements is such that whenall of the plates have been applied to thelbar, there is a comparativelyuniform divergence of the teeth, as will be evident from van-inspection of Figs. 1 and. 2. The final step in the process is'to fold the "flange '14 downwardly to the position shown in Fig. {1 thus reatly'increasing the strength of therakefil giving it a neat appearance. 1 .y 1 :After the rake headlhas-thus beenc'ompleteld, it is secured to the handle 10 by the rivet 11, andappropriate bracing means, hereina cu'rv'ed brace 26 is secured to the handle, by a rivet 27,.andtothe bar 12,

as by rivets 28. .As herein shown, these latterv rivets are passed through -the: openingspresented by two" of the .ieyelets, or

tubular rivets 24:." Asthe eyelets are arranged in staggered formation, the rivet28 at one end of the bar 12 willfnaturally pass through an eyelet 'of the upper row, JWhile the rivet-at the other end, will pass through aneyele tyof-thelowerrow (see Fig. .1). e l.

breaking at their points of attachment to the supporting bar, as there is no need of any welding operation. 7

Having thus described one embodiment of the invent/tan, but without limiting myself thereto, what I claim and desire by Letters J Patent to secure is:

1. In a rake, the combination of a handle, a bar extending transversely of and attached to said handle, a transverse series of plates presenting forwardly direct-ed teeth, said plates being provided with perforations, said bar presenting two forwardly -directed flanges between which said plates are received,-zamid fastening means extending from one of said flanges through Said perforations toward the other flange and securing said plates'to said bar. a g

In a rake, thecom'bination of a handle, a channel bar extending transversely of and attached tea'said handle, said channel-barpresenting two forwardlydirected flanges, and a tramsverse'series o ffkplates received between said flalnges and's'ecured to one ofsaid flanges, some of said plates presenting each a single tooth and some presenting'each two teeth.

'3. In afraik'e, the combination of a handle,

a channel bar extending transversely of and secured to said handle, said channel bar having a web along and closing its rear edge and upper and lower, forwardly directed, spaced flanges forming a slot open all along the front edge of said bar, and a transverse series of flat, flexible teeth extending rearwardly into said slot and disposed flatwise with relation to said flanges, said teeth being provided with perforations, and one of said flanges being provided with projections ex- 'tending't'hrough 'said'perforations toward the other of said. flanges and headed over onto said teeth adjacent to the inner face of the other flange, V V A In testimony whereof, I have signed my name to this specification.
